AI Dungeon: RPG & Story Maker

Review by eFreeware

If you have ever finished a tabletop session and wished the world would keep going after everyone packs up, AI Dungeon is built for exactly that itch. It is a text adventure where the story is generated as you play, so the world does not stop at the edge of a written script. You type what your character does or says, and the game answers with what happens next.

The pitch is aimed at people who like improvising more than following a plot someone else wrote. Readers, roleplayers and anyone who has spent an evening narrating a campaign for friends will recognize the rhythm here: describe an action, get a response, react to it. The developer, Latitude Inc., has been running this project since December 2019, and it has passed a million installs on Google Play with a 4.0 average from more than 106,000 ratings.

What I find appealing is that nothing about the premise demands prior experience with RPGs or writing. You can start with a scenario someone else built, choose a genre, and simply begin. The app is free to download and shows no ads, which matters when a session can run as long as you want it to.

How a session actually unfolds

The core loop is simple to describe and hard to predict in practice. You pick a prebuilt scenario or customize one to your taste, then play by typing what you want your character to do. The AI responds to those inputs and keeps generating the world around them, including the characters you meet along the way. There is no fixed set of dialogue options to choose from; the input is yours to write.

That freedom is the whole point. The developer describes an ever-evolving cast of NPCs and endless possibilities for getting past obstacles, finding new places and pushing the story in unexpected directions. Whether that lands depends on how much you enjoy writing your own prompts and reacting to whatever comes back.

Two systems sit underneath this to keep longer stories coherent. Story Cards and Memory Banks store context-dependent details and bring them up when they are relevant, so a character or a place you established earlier can resurface later. If a decision takes the story somewhere you regret, you can rewind it and try a different path. That rewind option is the feature I would lean on most in the early going, because it lowers the cost of experimenting with the input style the AI responds to best.

Scenarios, images and playing with friends

You do not have to invent a premise from nothing. Thousands of scenarios written by other players are available, spanning science fiction, romance, fantasy, horror and plenty of other genres. If none of them fit, you can create your own and share it with the community. For anyone who enjoys worldbuilding as much as playing, that side of the app can become the main draw.

The app also pairs with AI image generators, so you can create images on the fly to go with the story you are telling. It is a way of giving a scene a visual anchor rather than a separate creative tool, and it fits the general tone of the app: you describe something, and the software produces a version of it.

Multiplayer sessions let you adventure with friends, either collaborating on the same story or playing in your own directions within it. The AI keeps driving the narrative forward in either case. I would expect this to work best for groups who already enjoy telling stories together, since the fun comes from reacting to each other as much as from the text the app produces.

What the free version gives you and what premium adds

AI Dungeon is free to download and carries no ads. The free models come with what the developer calls a generous amount of context from the start, which is the memory the AI uses to keep track of what has happened. In practice that means you can play for as long as you like without paying, though the free models are the ones doing the writing.

In-app purchases are available, and the developer offers a week of premium without charge so you can try it before committing. Premium is presented as the step up for players who want more from their sessions, and the trial is the sensible way to judge whether the difference matters to you. It is worth treating that week as a real evaluation rather than a formality, since the free tier is already playable on its own terms.

The app carries a Teen content rating, which is a reasonable guide to the kind of material generated stories can drift into. Because the narrative follows your input, the tone of a session is largely in your hands.

The players this fits best

The people most likely to get value here are those who enjoy writing and improvising, and who are comfortable with text as the main medium. If you have played tabletop RPGs, written fan fiction or spent time in text-based adventures, the rhythm will feel familiar. If you like the idea of a story that reacts to you rather than one you follow, this is the format for it.

It also suits players who want variety without learning a new ruleset each time. The genre range across player-made scenarios means you can move from horror to romance to science fiction without changing apps, and the rewind option means a bad turn is not permanent. That combination is unusual, and it is the part of the design I would point to first when explaining the appeal.

The flip side is that the experience depends on what you put in. Typing is the interface, and the quality of a session tracks how willing you are to describe actions, set scenes and steer the AI. Someone looking for a story delivered to them, with defined levels and a fixed ending, will find the openness less of a feature and more of a demand.

A text RPG that rewards the effort you put in

AI Dungeon has been running long enough to have a settled identity: a free, ad-free text RPG where the AI responds to whatever you type and keeps the world moving. The scenario library, the memory systems and the rewind option all serve that single idea, and the multiplayer sessions extend it to groups. It is a coherent package rather than a collection of features.

My recommendation is straightforward. If you enjoy writing, roleplaying or improvising stories, install it and start with a prebuilt scenario before building your own. Give the free models a proper run, then use the week of premium to see whether the paid tier changes how you play. If you want a narrative game with a fixed script, this one asks for a kind of participation you may not be looking for.

For the right player, the appeal is that the story never runs out. That is a genuine difference from most games in the Adventure category, and it is why the app has held an audience since 2019.
